Speed, torque, and horsepower are three inter-related parameters in motor control. The speed of a motor, measured in revolutions per minute (rpm), defines a motor's ability to spin at a rate per unit ...

The topic of motors and motor control techniques is wide and varied. Part one of this two-part article will cover the principles of alternating-current (AC) motor operation and control. Part two will ...

When powering AC motors, the electrical supply can be at full power to run at full speed or at variable power to run at variable speed. Applications with varying loads benefit from the variable speed ...

Matching drive to motor is essential to gain the best combination of torque, speed, and efficiency. Selecting the right drive is essential to getting the best performance and efficiency from an ...

The Allen-Bradley PowerFlex 70 AC Drive is a proven solution designed for demanding industrial motor control tasks.

Today’s electric motor drive market offers system designers more options than ever before. On the AC side, motor drives provide highly flexible solutions with a growing array of features like variable ...

Speed control of an AC motor requires a three phase supply that can vary both voltage and frequency. Such a supply creates a variable speed rotating field in the stator that allows the rotor to spin ...

A synchronous and synchronous motors are the two main categories of ac motors. The induction motor is a common form of asynchronous motor and is basically an ac transformer with a rotating secondary.

In low-cost, high-speed motor applications, especially those inside the home, the universal motor dominates. They are as ubiquitous as the countertop blenders and the power tools they inhabit. But not ...

The way we control the speed of fan motors or pump motors has tremendously changed in the past two decades with the introduction of variable-frequency drives (VFDs), aka variable-frequency controllers ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

Indianapolis-Vertical, self-discharging, centrifugal separators must operate at high speeds for separation, then achieve high torque at low speeds for scraping. Classic designs are complicated, ...
